The distribution box is integrated in the reduction gear, part of an integrated propulsion system. It is designed as a combined speed reduction unit with common hydraulics for gear and propeller.
The compact powerpack that comes in five sizes has its own integral oil tank and is equipped with two electric motors driving load sensing pitch setting pumps and all necessary valves, filters and coolers.
The second pump will automatically start if the oil pressure drops below a pre-set level to provide the required level of redundancy.
